Lasers have been used in the medical field for many years and have been approved by the FDA for use in dentistry since 1994. All lasers work by delivering energy in the form of light. When used for surgical and dental procedures, the laser acts as a cutting instrument or a vaporizer of tissue that it comes in contact with. When used in teeth-whitening procedures, the laser acts as a heat source and enhances the effect of tooth-bleaching agents. Lasers can be used to remove tooth decay, treat tooth sensitivity, teeth whitening and treat gum disease.
Some of the advantages of using laser treatment in the above mentioned dental procedures are as follows:
- The laser itself causes less pain and provides its own analgesic effect; therefore, reducing the need for an actual injection
- May reduce anxiety in patients uncomfortable with the use of the dental drill
- Minimize bleeding and swelling during soft tissue treatments
